Thermoelastic State of a Ferritic Layer in a Quasistationary Electromagnetic Field

The electromagnetic, temperature, and mechanical fields formed in an elastic ferritic layer under the action of an electromagnetic field induced by a quasistationary current flowing in a plane parallel to the base of the layer are determined and studied. We establish the regularities of the distributions of intensities of the fields, heat release, ponderomotive forces, temperature, and stresses (in particular, in the vicinity of resonance frequencies) in a layer of magnetically soft Ni-Zn material depending on its thickness and the parameters of external action. The accumulated results can be used for the creation and development of the modes of operation of ferritic elements in electric and electronic devices. __________ Translated from Fizyko-Khimichna Mekhanika Materialiv, Vol. 41, No. 3, pp. 85–95, May–June, 2005.
